What does this fault code mean?
The fault code is intermittent, meaning it comes and goes. It concerns the front right side airbag, where the voltage in the circuit is too high for a longer period.

Possible causes
- Short-circuit to the power supply in the igniter cable or the connectors linking the right front side airbag to the SRS module
- A short to the power supply inside the right front side airbag

- 2Have a workshop check the connectors at the SRS module and at the front right side airbag for contact resistance and oxidation
